I got the substrate all changed over to Eco Earth.. I actually like the look a little better and will get some photos up soon. The pacman seems to enjoy it as well, he ate up three guppies after being set inside the tank with the new substrate. I do appreciate all the advise/help, don't care if I have to buy more stuff.. just so long as the little guy is happy. My humidity actually went up to around 85ish with the eco earth. I also got a low wattage uvb bulb I will be adding today. I had also read that if your pacman is getting a steady diet of fish, that it isn't needed to dust their food since the fish provides a steady calcium source, or is that untrue? My feeder fish (guppies, and smaller goldfish) are kept with my L182's so they get a steady diet of dried bloodworms ( more for the feeders), and they clean up whats left of the veggie wafers and once a week, shrimp pellets.
